86 olds cutlass ceira, no fuel thru TBI

Have a 86 olds cutlass ceira,2.5 cu in. auto,70,000 actual miles. Have replaced these parts with working parts from another friends car. Fuel pump,TBI unit,fuel pump relay, ECM, distributor. Even used auxilliary tank to put fuel to TBI, still no fuel passes thru the injector. What could I have possibly missed? Is there a way to bypass something to get fuel to flow out of injector. Car runs if u dump fuel in thru throttle body. How would u test for a fuel pulse at TBI? I,m stumped :cry: ,any ideas? :idea: thanks
